LOVE this game. very simple, yet stimulating. love the keyboard control. should be able to hit 'enter' to retry. also needs a Hi-Score board on Kongregate.
MOAR. omg, srsly. Make another. but, imo, I think you should be able to kill guards. it WOULD up the difficulty, but it'd still be nice to have as an option since you can't touch them normally anyway. and there should be some harder levels in there too. but yea, this game's definitely great!
